How are you running Renovate?

Self-hosted Renovate

If you're self-hosting Renovate, tell us which platform (GitHub, GitLab, etc) and which version of Renovate.

GitHub, Renovate 39.90.5

Please tell us more about your question or problem

When using uv and declaring a custom package index in pyproject.toml, using the name attribute is optional:

https://docs.astral.sh/uv/configuration/indexes/#defining-an-index

[[tool.uv.index]]
# Optional name for the index.
name = "pytorch"
# Required URL for the index.
url = "https://download.pytorch.org/whl/cpu"

However, Renovate errors out if name is missing (see Logs for the full entry):

"issues":{"tool":{"uv":{"index":{"0":{"name":"Required"}}}}}}

It looks like the related code is the following (there's no default for name):

renovate/lib/modules/manager/pep621/schema.ts

Lines 79 to 87 in ed5937b

	index: z
	.array(
	z.object({
	name: z.string(),
	url: z.string(),
	default: z.boolean().default(false),
	explicit: z.boolean().default(false),
	}),
	)

Setting name to .optional() should be easy, but a test should be added to verify functionality still works as expected as index.name is referenced in code.
